Currently HVCALL_RETARGET_INTERRUPT and HV_PARTITION_ID_SELF are defined
in pci-hyperv.c. However, similar to other hypercall related definitions
, it makes more sense to put them in the tlfs header file.
Nit: please keep the comma attached to the previous word - even if that
means you need to move the word with it to the next line to maintain line
limits.

Besides, these definitions are arch-dependent, so for the support of
virtual PCI on non-x86 archs in the future, move them into arch-specific
tlfs header file.

Thanks! I will fix the comma thing and add your Reviewed-by in next
version.
